Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, specifically relating to a building engineering floor and ground integrated assembly system and construction method. Background Technology

[0002] With the country vigorously promoting industrialized and prefabricated construction, the focus has gradually shifted from structural industrialization to interior decoration. A mature prefabricated decoration solution includes multiple aspects, with flooring being an important component. Prefabricated flooring (dry-construction flooring or raised flooring) differs from traditional decoration methods. It can be installed directly on the structural slab without the need for mortar leveling or self-leveling, without drilling or damaging the structure, and has high flatness, adaptable to various types of flooring materials.

[0003] Existing prefabricated raised floors mainly consist of a structural load-bearing layer, supports, and beams. The supports support the four corners of the structural load-bearing layer, and together with the beams, they raise the structural load-bearing layer to an appropriate height to form the raised structure. The structural load-bearing layer is usually square, often made of calcium silicate board. Several structural load-bearing layers are joined together, and after assembly, a thin decorative panel is applied to the top of the structural load-bearing layer. The decorative panel is generally connected and fixed to the structural load-bearing layer by adhesive. For example, the patent with authorization announcement number CN219387010U discloses a dry construction method for thin-laying floor tiles, which describes that "the upper surface of the raised floor is coated with an adhesive layer, and the back of the floor tiles is coated with a backing adhesive layer; the adhesive layer and the backing adhesive layer can improve the adhesion effect of the tile adhesive layer, making the connection between the raised floor layer and the floor tile layer more reliable."

[0004] While the aforementioned method achieves prefabricated dry construction, it doesn't truly realize pure dry construction and modular installation. Because the tiles are glued together, non-destructive removal is impossible, hindering subsequent maintenance and replacement. For example, a few years after renovation, due to leaks in heating pipes or other reasons, the tiles may need to be removed for repairs. After repair, the original tiles are unusable, and it's difficult to find the same type of tiles from several years ago on the market. This forces the owner to either completely remove and replace all the tiles or lower their expectations by choosing similar-looking tiles, resulting in an overall disharmony. Furthermore, for tenants of shops or rented properties, renovating the rented premises and replacing all the tiles would place a significant financial burden on them and be time-consuming and labor-intensive. In major cities where rents are high, saving renovation time and getting the property operational as quickly as possible is crucial.

[0005] Based on the above pain points, a detachable, replaceable, and reusable integrated assembly system and construction method for building floors and grounds are proposed. Summary of the Invention

[0006] To address the problems existing in the prior art, a comprehensive prefabricated system and construction method for building floors are provided. In this invention, the structural load-bearing layer and decorative panels are fixed without nails or glue, offering strong versatility and convenient installation and maintenance. Furthermore, the flooring is easily installed and disassembled as a whole, achieving rapid installation and removal, improving efficiency, saving costs, and realizing true dry construction and modular prefabricated installation. This invention has the advantages of being detachable, replaceable, and reusable.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] This technical solution proposes a comprehensive prefabricated system for building floors, comprising, from bottom to top, supporting and leveling components, a structural load-bearing layer, a magnetic layer, and decorative panels, wherein:

[0009] The structural load-bearing layer includes a composite plate, which includes a substrate. The upper and lower surfaces of the substrate are respectively attached with an upper metal plate and a lower metal plate that can be magnetically attracted. The composite plate has several through mounting holes for connecting with a support leveling component.

[0010] The support and leveling component includes a base, a bolt rod connected to the top of the base, and a cross groove for leveling provided on the top of the bolt rod; a sleeve is threaded onto the bolt rod, the outer wall of the sleeve has a support seat, and the top of the sleeve is inserted into the mounting hole; the support seat is positioned and supported on the lower surface of the lower metal plate.

[0011] The magnetic layer is magnetically attached to the surface of the upper metal plate of the composite board, forming a detachable magnetic structure.

[0012] The bottom of the decorative panel is glued and fixed to the upper surface of the magnetic layer.

[0013] Preferably, the upper surface of the support base is glued or magnetically fixed to the lower metal plate.

[0014] Preferably, the circumferential side of the composite plate is detachably connected with a rubber strip.

[0015] Preferably, the magnetic layer is made of rubber soft magnetic sheet.

[0016] Preferably, the decorative panel is floor tile or wood flooring.

[0017] This invention also proposes a construction method for a building construction floor and ground integrated assembly system, comprising the following steps:

[0018] S1: Factory processing;

[0019] S11: Cut the processed composite board to the specified dimensions;

[0020] S12: Mark and drill holes at the designed positions on the cut composite board to form installation holes;

[0021] S2: Load the composite panels onto the truck and transport them to the construction site, then unload them at the designated location; finally, manually carry the composite panels into the room to be decorated.

[0022] S3: Lay one of the composite panels face down on the ground, and then insert a matching number of support leveling components into the mounting holes of the composite panel; then flip the composite panel so that the base of the support leveling component faces down and is supported on the original building floor.

[0023] S4: Level the composite panel after installation;

[0024] S5: Repeat steps S3-S4 to complete the close assembly of multiple composite panels and form a structural load-bearing layer;

[0025] S6: Lay the magnetic layer onto the composite board, and then lay and fix the decorative panel on the upper surface of the magnetic layer; or first connect the magnetic layer and the decorative panel to form a whole, and then attach the whole to the surface of the composite board.

[0026] S7: Repeat step S6 above to complete the close-fitting installation of multiple decorative panels.

[0027] Preferably, in step S12, a clamping fixture is used to complete the process. The clamping fixture includes a base plate, with columns fixedly connected to the four corners of the base plate. A top plate for placing the composite board is fixedly connected to the top of each column. Side-pressing mechanisms and top-pressing mechanisms are respectively hinged to the columns on both sides. The side-pressing mechanism includes a first crank arm, which is L-shaped. A hinge pin is hinged at the corner of the first crank arm, and both ends of the hinge pin are connected to one side of the column. A side-pressing head is connected to the top of the first crank arm for pressing and fixing the side of the composite board. The first crank arm and the top plate... A tension spring connects the plates; the top-pressing holding mechanism includes a second crank arm, and a shaft is provided on the column on the other side. A guide groove is provided at the corner of the second crank arm, and the shaft is inserted into the guide groove, allowing the shaft to slide relative to the guide groove; a downward pressing head is connected to the top of the second crank arm for pressing and fixing the composite plate; a cylinder is fixedly connected to the top of the base plate, and an end plate is fixedly connected to the push rod of the cylinder. A support is connected to the top of the end plate, and the second crank arm is hinged to the support; a pull rope is connected to the first crank arm, and the bottom end of the pull rope is fixedly connected to the end plate.

[0028] Preferably, it also includes a positioning template, which has pre-drilled positioning holes. In use, the positioning template is placed on top of the composite board to assist workers in marking the positions of the mounting holes.

[0029] Preferably, in step S2, the process of manually lifting the composite board into the room to be decorated uses a handling clamp. The handling clamp includes a fixed clamping plate, the top of which is connected to an angle plate with an L-shaped cross-section. A first sleeve is fixedly connected to the outer wall of the angle plate. It also includes a movable clamping plate opposite to the fixed clamping plate, with a clamping space formed between the fixed and movable clamping plates for holding the composite board. The movable clamping plate is located inside the angle plate. The outer wall of the movable clamping plate... The system includes a fixed second sleeve and a support arm with a first and a second rotating shaft. The first rotating shaft is connected to the first sleeve, and the second rotating shaft is connected to the second sleeve. The support arm is L-shaped, with a lever arm connected to one end and a handle connected to the other end. The clamping angle between the lever arm and the support arm is obtuse. When the lever arm is rotated, it causes the support arm to rotate, which in turn causes the movable clamping plate to move closer to the fixed clamping plate, thus clamping the composite plate.

[0030] Preferably, friction pads are attached to the surfaces of both the movable clamping plate and the fixed clamping plate; the fixed clamping plate and the movable clamping plate are provided with insertion holes, and positioning pins are inserted into the insertion holes. In use, the positioning pins pass through the insertion holes and a certain mounting hole of the composite plate to prevent detachment.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] 1. In this invention, the structural load-bearing layer and the decorative panel are fixed without nails or glue, offering strong versatility and convenient installation and maintenance. Furthermore, the flooring is easy to install and disassemble as a whole, achieving quick installation and removal, improving efficiency, saving costs, and realizing true dry construction and modular assembly. The magnetic layer in this embodiment not only facilitates disassembly and installation but also provides shock absorption, reduces noise, and minimizes the feeling of hollowness.

[0033] 2. The structural load-bearing layer of this invention adopts a composite plate structure. The composite plate consists of a substrate in the middle and upper and lower metal plates bonded to the upper and lower surfaces of the substrate, forming a sandwich structure. The upper and lower metal plates provide better strength to the substrate, resulting in better overall stability, good impact and bending resistance, and resistance to deformation. During use, it is not afraid of impacts from people jumping or heavy objects falling, and the ground is not easily damaged, resulting in a long service life. In addition, the upper and lower metal plates not only increase strength but also facilitate adsorption with the magnetic layer, serving as a carrier for magnetic adsorption, achieving two benefits at once.

[0034] 3. In this invention, the composite panel is also provided with a fitting groove, in which a flexible rubber strip can be detachably installed. In this way, when the composite panel is assembled, the rubber strip can play a certain role in shock absorption, reducing the noise generated by collision and compression between the composite panels and improving comfort. In addition, the setting of the rubber strip is equivalent to forming an expansion joint between the composite panels, which can provide a certain displacement compensation with the change of seasons and indoor temperature, avoiding the damage to the surface flatness of the structural stress layer caused by mutual compression deformation between the composite panels due to thermal expansion and contraction, and thus problems such as bulging of the decorative panel.

[0035] 4. This invention also incorporates a clamping fixture during processing. This fixture includes a side-pressing mechanism and a top-pressing mechanism. During drilling, activating the cylinder simultaneously drives both the side-pressing and top-pressing mechanisms to press and position the side of the composite board and fix its top surface downwards. This achieves pressing and fixing in both horizontal and vertical directions, enabling rapid positioning, rapid clamping, and excellent clamping results, eliminating the need for additional positioning. This fixture allows for rapid positioning and clamping of the composite board. Furthermore, the clamping fixture includes a positioning template with pre-drilled holes. When clamping the composite board, the positioning template is also clamped and positioned simultaneously. Workers can then use the positioning holes on the template to quickly determine the positions of the mounting holes on the composite board, significantly improving processing efficiency.

[0036] 5. The composite board in this invention can be designed to be a large-size structure of 1.0*1.0m-1.5*1.5m, which is larger than the existing calcium silicate board (generally 0.6*0.6m). This allows for rapid installation over a large area, improving construction efficiency. However, the large size of the composite board is not conducive to worker handling. Therefore, the inventors have also designed a matching handling clamp. The handling clamp adopts a structure of fixed clamp and movable clamp. Utilizing the lever principle, the fixed clamp and movable clamp can be squeezed together to clamp and fix the composite board. In addition, considering that the upper and lower surfaces of the composite board are both metal plates and are relatively smooth, the inventors have also designed a friction pad and a safety pin. The friction pad increases the friction force, and the safety pin realizes the through-hole connection between the handling clamp and the composite board, which can improve safety. In case the handling clamp slips off the composite board, the safety pin can effectively prevent the composite board from accidentally falling and injuring the worker's feet. This tool can improve the efficiency of worker handling, requiring only one person per board, eliminating the need for two people to carry it, and increasing construction speed.

Therefore, they should not be construed as limitations of the present invention.

[0060] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0061] like Figures 1-15 As shown in the figure, this embodiment proposes a comprehensive prefabricated system for building floors, including a support and leveling component A1, a structural load-bearing layer A2, a magnetic layer A3, and a decorative panel A4 arranged sequentially from bottom to top. The support and leveling component A1 is used to support the original building floor and plays a dual role of support and leveling. The structural load-bearing layer A2 serves as the base surface for laying the decorative panel A4, providing both load-bearing support and a base surface. The decorative panel A4 and the structural load-bearing layer A2 are connected by magnetic attraction through the magnetic layer A3, and the decorative panel A4 serves a decorative function.

[0062] The following is a further detailed explanation of each of the above parts:

[0063] The structural load-bearing layer A2 includes a composite plate A21, which includes a substrate A211. An upper metal plate A212 and a lower metal plate A213, which can be magnetically attracted, are respectively attached to the upper and lower surfaces of the substrate A211. The upper metal plate A212 and the lower metal plate A213 are pressed and fixed onto the upper and lower surfaces of the substrate A211, and the three together form a sandwich composite plate A21. The composite plate A21 has several through-holes A216, which are used to connect with the support and leveling component A1. The mounting holes A216 can be opened circumferentially along the composite plate A21, and the number and spacing of the mounting holes A216 are adjusted according to the size of the composite plate A21.

[0064] In this embodiment, the composite board A21 can be designed as a large-size structure of 1.0*1.0m-1.5*1.5m, such as 1.2*1.2m, which is larger than the existing calcium silicate board (generally 0.6*0.6m). This allows for rapid installation over a large area during paving, improving construction efficiency.

[0065] In this embodiment, the structural load-bearing layer A2 adopts a composite plate A21 structure. The composite plate A21 consists of a base plate A211 in the middle and upper and lower metal plates A213 bonded to the upper and lower surfaces of the base plate A211, forming a sandwich structure. The upper metal plate A212 and lower metal plate A213 can provide better strength to the base plate A211, resulting in better overall stability, good impact and bending resistance, and resistance to deformation. During use, it is not afraid of impacts from people jumping or heavy objects falling, and the ground is not easily damaged, resulting in a long service life. In addition, the upper metal plate A212 and lower metal plate A213 not only increase strength, but also facilitate adsorption with the magnetic layer A3, serving as a carrier for magnetic adsorption, achieving two benefits at once.

[0066] The leveling support A1 includes a base A11, which is used to support the original building floor. A bolt rod A12 is connected to the top of the base A11, and the top of the bolt rod A12 has a cross groove A14 for leveling. A sleeve A13 is threaded onto the bolt rod A12, and the outer wall of the sleeve A13 has a support seat A15. The top of the sleeve A13 is inserted into a mounting hole A216. The support seat A15 is positioned and supported on the lower surface of the lower metal plate A213. During leveling, the bolt rod A12 can be rotated by turning the cross groove A14 with a screwdriver, thereby allowing the bolt rod A12 to move up and down, thus completing the leveling work.

[0067] In this embodiment, the magnetic layer A3 is magnetically attached to the surface of the upper metal plate A212 of the composite board A21, forming a detachable magnetic structure, which facilitates future maintenance and replacement of the decorative panel A4.

[0068] In this embodiment, the bottom of the decorative panel A4 is glued and fixed to the upper surface of the magnetic layer A3. During construction, the magnetic layer A3 can be glued to the bottom of the decorative panel A4 at intervals or fully covered to connect the magnetic layer A3 and the decorative panel A4 into one unit, and then the entire panel is laid and magnetically attached to the surface of the structural load-bearing layer A2.

[0069] In this embodiment, to facilitate the installation and assembly of the support leveling component A1 and the composite plate A21, the upper surface of the support base A15 is glued or magnetically fixed to the lower metal plate A213. For example, using adhesive, during assembly, a layer of adhesive is first applied to the surface of the support base A15, and then the support leveling component A1 is inserted into the mounting hole A216, using adhesive to fix the support leveling component A1 to the composite plate A21. As a better option, in this embodiment, it is preferable to use magnetic attraction between the support base A15 and the composite plate A21. For example, a layer of adhesive-backed soft magnetic pad is pasted on the surface of the support base A15, and then the magnetism of the adhesive-backed soft magnetic pad is used to connect the support base A15 to the lower metal plate A213. Using an adhesive-backed soft magnetic pad can also play a certain role in shock absorption and cushioning, reducing abnormal noise.

[0070] The upper metal plate A212 and the lower metal plate A213 are made of magnetic steel plate structure.

[0071] Considering that the composite panels A21 are rigidly connected, the collision noise may be relatively loud when walking. In addition, the rigid connection has no expansion joints, which may cause problems when thermally expanding and contracting. Therefore, further improvements have been made. Rubber strips A214 are detachably connected to the circumferential side of composite panels A21, and fitting grooves A215 are opened around the perimeter of composite panels A21. Fitting grooves A215 include, but are not limited to, dovetail grooves, T-grooves, or spherical grooves. The rubber strips A214 are made of flexible material and can be inserted into the fitting grooves A215. Then, adjacent composite panels A21 are connected by rubber strips A214, changing the rigid connection into a flexible connection and providing a certain amount of expansion and contraction.

[0072] In this embodiment, a fitting groove A215 is opened on the composite panel A21, and a flexible rubber strip A214 is detachably installed in the fitting groove A215. In this way, when the composite panel A21 is assembled, the rubber strip A214 can play a certain role in shock absorption, reducing the noise generated by the collision and compression between the composite panels A21, and improving comfort. In addition, the setting of the rubber strip A214 is equivalent to forming an expansion joint between the composite panels A21, which can provide a certain displacement compensation with the change of seasons and indoor temperature, avoiding the damage to the surface flatness of the structural load-bearing layer A2 caused by the mutual compression and deformation between the composite panels A21 due to thermal expansion and contraction, and thus the bulging of the decorative panel A4.

[0073] In this embodiment, the magnetic layer A3 is made of soft rubber magnetic sheet, which can be cut to any size, making it very convenient.

[0074] In this embodiment, the decorative panel A4 is a floor tile, wood flooring, or other board material.

[0075] In this embodiment, the present invention also proposes a construction method for a building engineering floor and ground integrated assembly system, comprising the following steps:

[0076] S1: Factory processing; Composite board A21 is processed by the manufacturer.

[0077] S11: Cut the processed composite board A21 to the specified dimensions;

[0078] S12: Mark and drill holes at the designed positions on the cut composite board A21 to form mounting holes A216;

[0079] S2: Load composite board A21 onto a truck and transport it to the construction site, then unload it at the designated location; then manually carry composite board A21 into the room to be decorated;

[0080] S3: Lay one of the composite panels A21 upside down on the ground, and then insert a matching number of support leveling components A1 into the mounting holes A216 of the composite panel A21; then flip the composite panel A21 so that the base A11 of the support leveling component A1 faces down and is supported on the original building ground; in this step, the sleeve A13 of the support leveling component A1 is inserted into the mounting hole A216. Note that the top of the sleeve A13 does not extend beyond the surface of the upper metal plate A212.

[0081] S4: Level the installed composite panel A21; during leveling, the composite panel A21 is raised or lowered by turning the cross groove A14 at the top of the bolt rod A12, and the leveling process is finally achieved.

[0082] S5: Repeat steps S3-S4 to complete the close splicing of multiple composite panels A21 to form the structural load-bearing layer A2;

[0083] S6: Lay the magnetic layer A3 onto the composite board A21, and then lay and fix the decorative panel A4 on the upper surface of the magnetic layer A3; or first connect the magnetic layer A3 and the decorative panel A4 to form a whole, and then attach the whole to the surface of the composite board A21.

[0084] S7: Repeat step S6 above to complete the close-fitting installation of multiple decorative panels A4.

[0085] As a preferred technical solution, step S12 uses a clamping fixture B1 to complete the process. The clamping fixture B1 includes a base plate B11, with columns B12 fixedly connected to the four corners of the base plate B11. A top plate B13 for placing the composite board A21 is fixedly connected to the top of the columns B12. With the center of the base plate B11 as the axis, a side-pressing mechanism and a top-pressing mechanism are hinged to the columns B12 on both sides of the axis. The side-pressing mechanism includes a first crank arm B14, which is L-shaped. A hinge pin B26 is hinged at the corner of the first crank arm B14, with both ends of the hinge pin B26 connected to a side column B12. This allows the first crank arm B14 to rotate around the hinge pin B26. A side pressure head B16 is connected to the top of the first crank arm B14 for pressing and fixing the side of the composite plate A21. A tension spring B22 connects the first crank arm B14 and the top plate B13. In the initial state, under the action of the tension spring B22, the first crank arm B14 is in an open state and no longer presses the side of the composite plate A21. (See attached diagram.) Figure 12 As shown; the top-pressing holding mechanism includes a second crank arm B15, and a shaft B27 is provided on the other side column B12. The shaft B27 is fixedly connected to the column B12. A guide groove B25 is provided at the corner of the second crank arm B15, and the shaft B27 is inserted into the guide groove B25. The shaft B27 can slide relative to the guide groove B25. The second crank arm B15 has an eight-shaped structure and is welded from two branch rods. The included angle between the two branch rods is an obtuse angle. The top of the second crank arm B15 is connected to a pressing head B17, which is used to press down and fix the composite plate A21. The vertical section of the second crank arm B15 also plays a positioning role. During the rotation of the second crank arm B15, the vertical section of the second crank arm B15 gradually approaches the top plate B13. The edge of the second crank arm B15 can limit the edge of the composite plate A21, which plays a role in aligning the edges. A cylinder B19 is fixedly connected to the top of the base plate B11. An end plate B20 is fixedly connected to the push rod of the cylinder B19. A support B24 is connected to the top of the end plate B20. The second crank arm B15 is hinged to the support B24. A pull rope B21 is connected to the first crank arm B14, and the bottom end of the pull rope B21 is fixedly connected to the end plate B20. The main function of the pull rope B21 is: during the downward pulling of the push rod, the pull rope B21 pulls the first crank arm B14 to rotate against the elastic force of the tension spring B22. The pull rope B21 can be used to make the first crank arm B14 firmly press the side of the composite plate A21.

[0086] It should be noted that, in order to facilitate marking and drilling, the clamping fixture B1 also includes a positioning template B18. The positioning template B18 is provided with pre-drilled positioning holes, which are made according to the design dimensions. In use, the positioning template B18 is placed on top of the composite board A21 to assist the worker in marking the position of the mounting hole A216. In this way, the worker only needs to mark the position of the mounting hole A216 on the composite board A21 by drawing a circle around the positioning hole with a marker according to the position of the positioning hole.

[0087] In this embodiment, a clamping fixture B1 is designed, which includes a side-pressing mechanism and a top-pressing mechanism. When drilling, the cylinder B19 is activated, which simultaneously drives the side-pressing mechanism and the top-pressing mechanism to press and position the side of the composite board A21 and press and fix its top surface. This achieves pressing and fixing in both horizontal and vertical directions, enabling rapid positioning, rapid clamping, and good clamping effect without the need for additional positioning. Using this fixture, the positioning and clamping of the composite board A21 can be quickly achieved. In addition, the clamping fixture B1 also includes a positioning template B18 with pre-drilled holes. When clamping the composite board A21, the positioning template B18 can be clamped and positioned simultaneously. This allows the operator to use the positioning holes on the positioning template B18 to mark the positions of the mounting holes A216 on the composite board A21, which can greatly improve processing efficiency.

[0088] In addition, in this embodiment, in step S2, the composite panel A21 is manually lifted and transported to the room to be decorated using a handling clamp C. The handling clamp C includes a fixed clamping plate C1, with a corner plate C2 connected to its top. The corner plate C2 has an L-shaped cross-section. A first sleeve A13 is fixedly connected to the outer wall of the corner plate C2. It also includes a movable clamping plate C3 opposite to the fixed clamping plate C1, forming a clamping space between the fixed clamping plate C1 and the movable clamping plate C3 for holding the composite panel A21. The movable clamping plate C3 is located inside the corner plate C2. A second sleeve A13 is fixedly connected to the outer wall of the movable clamping plate C3. Furthermore, it includes a support arm C10, on which a first rotating shaft C6 and a second rotating shaft C7 are mounted. The first rotating shaft C6 is connected to the first sleeve A13. The first shaft C7 is connected to the second sleeve A13. The support arm C10 is L-shaped. In use, the support arm C10 can rotate around the hinge point formed at the first shaft C6. When it rotates, it is equivalent to forming a lever fulcrum at the first shaft C6 and a lever arm at the second shaft C7. When the support arm C10 rotates, it can drive the movable clamping plate C3 to deflect inward, thereby realizing the clamping action. The end of the support arm C10 is connected to the lever arm C11, and the end of the lever arm C11 is connected to the handle rod C12. The clamping angle between the lever arm C11 and the support arm C10 is obtuse. When the lever arm C11 is rotated, the lever arm C11 drives the support arm C10 to rotate, thereby driving the movable clamping plate C3 to move closer to the fixed clamping plate C1, thus completing the clamping of the composite plate A21.

[0089] In this embodiment, both the side pressure head B16 and the downward pressure head B17 are bolted, which can be adjusted to adjust the clamping force.

[0090] In addition, side baffles B23 are provided on both sides of the top plate B13. The side baffles B23 serve as limiting and positioning devices. During use, they guide and limit the two sides of the composite plate A21. Together with the side pressure head B16 and the downward pressure head B17, they can achieve all-round positioning and fixing.

[0091] During handling, the worker holds the handle C12 with one hand and lifts it with one hand, keeping the composite board A21 close to one side of the body, thus moving the composite board A21.

[0092] In this embodiment, friction pads C13 are attached to the surfaces of both the movable clamping plate C3 and the fixed clamping plate C1. Insertion holes C8 are provided on both the fixed clamping plate C1 and the movable clamping plate C3, and a positioning pin C9 is inserted into each insertion hole C8. During use, the positioning pin C9 passes through the insertion hole C8 and a mounting hole A216 of the composite plate A21 to prevent detachment and provide safety. The positioning pin C9 can be a high-strength bolt of appropriate diameter.

[0093] As mentioned above, the composite plate A21 in this embodiment is relatively large. The large size of the composite plate A21 makes it difficult for workers to handle. Therefore, a matching handling clamp C was designed. The handling clamp C adopts a structure of a fixed clamping plate C1 and a movable clamping plate C3. Utilizing the lever principle, the fixed clamping plate C1 and the movable clamping plate C3 can be pressed together to clamp and fix the composite plate A21. In addition, considering that the upper and lower surfaces of the composite plate A21 are both metal plates and are relatively smooth, the inventors also designed a friction pad C13 and a safety pin. The friction pad C13 increases the friction force, and the safety pin enables a through-hole connection between the handling clamp C and the composite plate A21, improving safety. In case the handling clamp C slips off the composite plate A21, the safety pin can effectively prevent the composite plate A21 from accidentally falling and injuring the worker's feet. This tool can improve the efficiency of worker handling; one person can handle one plate, eliminating the need for two people to lift and transport, thus increasing construction speed.
